The committee then chooses whether to pursue articles of impeachment against the accused official and report them to the full House. If the articles are adopted (by simple majority vote), the House appoints Members by resolution to manage the ensuing Senate trial on its behalf.
A quadrant is one-fourth of a circle. When you bake an apple pie and then cut it equally so that you and three of your friends get pieces that are the same size, you'll each get a quadrant of the pie. When a circle is evenly divided into four sections by two perpendicular lines, each of the four areas is a quadrant.
In a tourney whose selection was very homogeneous (for example, 128 players all within UTR 0.5 of each other), the compass quadrants would mean little, as the draw itself has competitiveness built in.
